property group_snapshot

property group_snapshot_id

property host

All cleanable VO must have a host property/attribute.

property id

property metadata

model

alias of Snapshot

property name

obj_extra_fields = ['name', 'volume_name']

obj_load_attr(attrname)

Load an additional attribute from the real object.

This should load self.$attrname and cache any data that might be useful for future load operations.

obj_reset_changes(fields=None)

Reset the list of fields that have been changed.

Parameters:

• fields – List of fields to reset, or “all” if None.

• recursive – Call obj_reset_changes(recursive=True) on any sub-objects within the list of fields being reset.

This is NOT “revert to previous values”.

Specifying fields on recursive resets will only be honored at the top level. Everything below the top will reset all.

obj_what_changed()

Returns a set of fields that have been modified.

property progress

property project_id

property provider_auth

property provider_id

property provider_location

save()

Save the changed fields back to the store.

This is optional for subclasses, but is presented here in the base class for consistency among those that do.

classmethod get_all(context, filters, marker=None, limit=None, sort_keys=None, sort_dirs=None, offset=None)

Get all snapshot given some search_opts (filters).

Special filters accepted are host and cluster_name, that refer to the volume’s fields.
